JA-5H175 Accelerometer

Quartz Servo Accelerometers

JA-5H175 Accelerometer

The 175 ℃ JA-5H175 series accelerometers have been developed to meet the increasing high temperature needs of downhole applications. JA-5H175 is widely used in conventional drilling and unconventional applications. JAE is one of the established key suppliers of high accuracy quartz accelerometers to downhole applications. Using our wealth of knowledge, we have extended the accelerometer operating temperature range to provide reliable sensor for long term operation without compromising performance.
